ELASTIC WIRE SUPPORT FOR BEDS OR'SEATS.

SPECIFICATION forming part of Letters Patent No. 526,860, dated October2, 1894.

(No model.) Patented in Germany September 13, 1892 No. 68,639 in BuginSwitzerland Ja ua y 24, 1893, No. 6,319; in Belgium February 1, 1894,No. 103,226,

and in Austria-Hungary June 17, 1894, No. 6,230 and No. 19,733.

To all whom it may concern:

Be it known that I, GUSTAV DOMINICK, a subject of the King of Prussia,and a resident of Cologne, in the Kingdom of Prussia, Empire of Germany,have invented certain new and useful Improvements in Elastic WireSupports for Beds or Seats, (patented in Germany, No. 68,639, datedSeptember 13, 1892; in England, No.1, 480, dated January 8, 1893; inSwitzerland, No. 6,319, dated January 24, 1893; in Belgium, No. 103,226,dated February 1, 1894, and in Austria-Hungary, No. 6,230 and No.19,733, dated June 17, 1894,) of which the following is a specification,reference being had to the accompanying drawings, in Which Figure 1 is aside elevation; Fig. 2, a plan view, and Fig. 3 a cross sectionalelevation of a spring mattress constructed according to my invention.Fig.4 shows oneof the trans verse springs; and Fig. 5 one of thelongitudinal springs employed in my invention.

Similar letters refer to similar parts through out the several views.

My invention consists in providing within a suitable frame, two seriesof springs running cross-wise of each other andessentially parallel tothe sides of the frame, the springs of one series being fastened to theframe at both ends, while the springs of the other series are secured atone end only, the other ends thereof being guided in eyes formedpreferably by twisting the springs of the first series into coils, aswill be more readily understood by reference to the drawings.

To the iron or wooden frame I) b, I secure at the shorter sides a seriesof parallel longitudinal coiled Wire springs a. (See Fig. 5.)

The coils are wound obliquely to the longitudinal axis of the spring,thus permitting the ends of the wires ato be inserted from the side, aswill be presently described.

Longitudinal iron rods or bars b are. fitted on both sides of the frameb.- To these rods I secure one end of each of a second series of springsa, made as shown in detail in Fig. 4. It will be observed that one endportion 'of these wire springs is coiled on the rods b, While theremaining portion of the springs is substantially straight and is passedthrough the spirals of the several longitudinal springs c. The'free endsof the springs a are bent into eyes (see Fig. 4) so that they cannotslip out of the longitudinal springs c. It will be obvious that the freeends of the springs a are capable of sliding in the coils of the Springs0, and will be constantly kept the same distance apart by the saidcoils.

The operation of the device will be readily understood. The mattressformed by the springs or. 0 will yield to the slightest pressure, as thetwo series of springs are not rigidly connected, but each series iscapable of yielding to a certain extent, independently of the otherseries. The springs a, being however guided in the springs c, the wholemattress Will always form a slightly curved or plane surface, and thesprings of both series will supplement each other in their action.

It will be obvious that my invention is applicable to cushions forvarious articles of furniture, for carriage seats, and the like.

What I claim, and desire to secure by Letters Patent, is

A spring support for beds and seats, consisting of a suitable frame, aseries of springs arranged lengthwise of the frame and secured theretoat both ends, and another series of springs placed crosswise of theframe, each spring of the second series being fast at one end and havingits other end freely guided in suitable eyes formed on, or attached to,

the springs of the first series, for the purpose set forth.

In witness whereof I hereunto set my hand in presence of two witnesses.

- GUSTAV DOMINICK.
